ABSTRACT:
A thermoplastic resin comprises a graft copolymer obtained by graft-polymerizing one or more kinds of vinyl monomer onto a compound rubber, wherein that compound rubber is obtained by inseparably entangling a polyalkyl(meth)acrylate rubber and a modified polyorganosiloxane rubber, the modification being obtained by radical polymerization of 1 to 15 parts by weight of at least one monomer selected from the group consisting of a polyfunctional unsaturated compound having at least one (meth) acryloyloxy group and a polyfunctional unsaturated compound having a cyanuric acid or isocyanuric acid skeleton in the presence of a polyorganosiloxane rubber.
